+# Tool parity: Google's agent vs Claude Code
+
+Goal: let Google's agent CLI do everything Claude Code can, by building
+the missing capabilities as small CLI tools in this repo. The agent
+calls them through its shell tool, so every tool follows the house
+rules: **text in, verifiable artifacts out**, single static Go binary,
+self-explanatory output.
+
+**Which Google agent?** Legacy `gemini-cli` is auth-dead for personal
+accounts (verified again 2026-08-05, see infra-Doc
+`hosts/brasse-linux01.md`). The real target is **`agy` (Antigravity
+CLI)** — live-tested in section 2, and its toolset differs from the
+old Gemini CLI docs. Section 1's table is kept for reference since
+Gemini CLI still exists in API-key mode.
+
+A design rule that fell out of the live test: **a dedicated binary
+beats ad-hoc shell because of approval prefixes.** agy (like Claude
+Code) allowlists commands by prefix — `notifyr …` can be approved once
+and forever, while every hand-rolled `for i in $(seq …); do curl …`
+loop is a unique string that needs fresh human approval. Small stable
+CLIs are therefore not just convenience: they are what makes
+unattended agent operation possible at all.
+
+Sources: Gemini CLI tools reference (<https://geminicli.com/docs/reference/tools/>),
+Claude Code's toolset as of 2026-08, live probing of `agy` 1.1.9.
+
+## 1. Already at parity — nothing to build
+
+| Capability | Claude Code | Gemini CLI |
+|---|---|---|
+| Read/write/edit files | `Read` / `Write` / `Edit` | `read_file` / `write_file` / `replace` |
+| Find files / search text / list dirs | `Glob` / `Grep` | `glob` / `grep_search` / `list_directory`, plus `read_many_files` |
+| Shell, incl. background processes | `Bash` (+ background tasks) | `run_shell_command` (+ background processes) |
+| Web | `WebFetch` / `WebSearch` | `web_fetch` / `google_web_search` |
+| Ask the user a structured question | `AskUserQuestion` | `ask_user` |
+| Plan mode | `EnterPlanMode` / `ExitPlanMode` | `enter_plan_mode` / `exit_plan_mode` |
+| Skills / slash commands | `Skill` (`.claude/skills`) | `activate_skill` (`.gemini/skills`) |
+| Persistent memory | file-based memory dir | `save_memory` (simpler, but exists) |
+| Todo/task tracking | `TaskCreate`/`TaskUpdate`/… | `write_todos`, `tracker_*` (experimental) |
+| MCP servers + resources | MCP tools, `ListMcpResources`/`ReadMcpResource` | MCP tools, `list_mcp_resources`/`read_mcp_resource` |
+| Subagents | `Agent` (background, custom types) | subagents (experimental) — weaker, see `fanout` below |
+
+Not worth replicating (harness-internal to Claude Code, no value as a
+CLI): `ToolSearch`, `EndConversation`, `ReportFindings`,
+`ShareOnboardingGuide`, `DesignSync`, remote cloud execution.
+
+## 2. Live test 2026-08-05: `agy` (Antigravity CLI 1.1.9)
+
+Tested interactively in a tmux session (Google AI Pro account, model
+Gemini 3.6 Flash). Its 19 built-in tools, self-enumerated:
+
+`ask_permission`, `ask_question`, `define_subagent`, `generate_image`,
+`grep_search`, `invoke_subagent`, `list_dir`, `list_permissions`,
+`manage_subagents`, `manage_task`, `multi_replace_file_content`,
+`read_url_content`, `replace_file_content`, `run_command`, `schedule`,
+`search_web`, `send_message`, `view_file`, `write_to_file`.
+
+What this changes vs the old Gemini CLI picture:
+
+- **agy has real subagents** (`invoke_subagent`/`define_subagent`/
+  `manage_subagents` + `send_message`) and background-task management
+  (`manage_task`). → `fanout` demoted further; probably never needed.
+- **agy has `schedule`** — one-shot timer or cron expression that wakes
+  the agent with a prompt (same idea as Claude's `ScheduleWakeup`).
+  Confirmed limits, from its schema: it cannot run commands itself,
+  it is **in-memory and dies with the session**, and it cannot reach
+  the phone. → `cronr` (persistent systemd timers) and `notifyr` are
+  still needed; `schedule` complements them within a session.
+- **agy has `generate_image`** — a *reverse* gap: Claude Code has no
+  native image generation. Nothing to build; just worth knowing.
+- No MCP-resource tools, no memory tool and no glob in its toolset
+  (grep/list_dir cover finding files).
+
+Behavior tests run in a scratch arena:
+
+| Test | Result |
+|---|---|
+| Enumerate tools | Clean list of 19 (above) |
+| Edit a text file | Worked, auto-approved in trusted folder |
+| Edit a Jupyter cell, keep `.ipynb` valid | **Passed** — it wrote a `python3 -c` json script rather than text-replacing. Notebook stayed valid. Cost: a per-command approval each time → `nbcell` demoted to nice-to-have (stable prefix + no ad-hoc python). |
+| Wait for a file to appear | Worked via a hand-rolled `for … sleep 1` shell loop — a unique command string needing fresh approval. → exactly the `waitfor` case. |
+| Asked agy which CLI tools *it* wants for the homelab | Its list: ntfy client, `tea` (Gitea CLI), `skopeo`/`crane` (registry), `ofelia`/cron daemon, `ctop`-style fleet status — near-1:1 with section 4, and it independently made the approval-prefix argument. |
+
+**Buy before build:** agy's suggestions overlap with off-the-shelf
+tools. Evaluate first: `tea` (official Gitea CLI — but it does not read
+the Pi5's zst action logs and has no `wait-quiet`, which stay
+`giteactl`'s reason to exist, possibly as a thin layer *on top of*
+`tea`), `skopeo`/`crane` (cover most of `reghelper` — remaining value
+is prune *plans* and size summaries), `ctop` (interactive TUI, not
+agent-friendly output — `fleet` still wins for agents).
+
+## 3. Gaps → tools to build
+
+Ordered by expected value. Each becomes its own folder + binary +
+README, per repo convention.
+
+### 3.1 `cronr` — scheduled/recurring runs *(Claude: `CronCreate`/`CronList`/`CronDelete`, `/loop`)*
+
+agy's built-in `schedule` dies with the session (see section 2).
+`cronr` manages **systemd user timers** so an agent can create
+recurring or one-shot jobs that survive session exit and reboot
+(including "run this prompt every morning" via `agy -p …`).
+
+```
+cronr add nightly-ci-check --schedule "*-*-* 07:00" --cmd 'agy -p "check CI status and notify"'
+cronr add once-reboot-check --at "2026-08-06 03:00" --cmd '…'   # one-shot
+cronr list                    # name, schedule, next run, last result
+cronr logs nightly-ci-check   # journalctl for the unit
+cronr rm nightly-ci-check
+```
+
+Output prints the generated unit files so the result is verifiable.
+No daemon of its own — systemd does the running.
+
+### 3.2 `waitfor` — block until a condition holds *(Claude: `Monitor`)*
+
+Turns "poll every N seconds" into a single blocking tool call, so the
+agent doesn't burn turns polling.
+
+```
+waitfor --cmd "curl -sf https://gitea.brasse-pc.eu/api/healthz" --interval 30s --timeout 20m
+waitfor --cmd "ssh pi5 docker ps --format '{{.Names}}'" --matches 'gitea' --timeout 10m
+waitfor … --then 'notifyr send --msg "gitea is back up"'
+```
+
+Exit 0 = condition met, exit 3 = timeout; last output is printed either
+way. `--then` runs a command on success (composes with `notifyr`).
+
+### 3.3 `notifyr` — push notifications, send **and read** *(Claude: `PushNotification`)*
+
+The ntfy server **already runs on the Pi5** and is the house-wide
+notification bus (topics like `Info`, `pi5-server-fel`, `ci-fel` — see
+infra-Doc `services/observability.md`). `notifyr` is a thin client so
+every agent uses it the same way:
+
+```
+notifyr send --topic ci-fel --title "Build failed" --msg "agent-tools arm64 test: FAIL" --priority high
+notifyr read --topic pi5-server-fel --since 2h     # poll mode: what has alerted lately?
+```
+
+`read` (ntfy's `?poll=1&since=…`) is the underrated half: it lets an
+agent *check what the infra has been complaining about* before/after a
+change. Config (`~/.config/notifyr/config.json`): server URL + token.
+
+### 3.4 `pagepub` — publish an HTML/Markdown report to a URL *(Claude: `Artifact`)*
+
+Claude Code can publish reports as web pages; Gemini cannot. `pagepub`
+rsyncs a file to a static-file host on the Pi5 (nginx container behind
+NPM, e.g. `pages.brasse-pc.eu`) and prints the stable URL.
+
+```
+pagepub publish report.html --slug ci-report     → https://pages.brasse-pc.eu/ci-report/
+pagepub publish notes.md --slug pi5-audit        # .md rendered to HTML with built-in template
+pagepub list | rm <slug>
+```
+
+Requires the static host to exist first (small infra task; goes in
+infra-Doc + NPM proxy host via `npmctl`).
+
+### 3.5 `nbcell` — Jupyter notebook editing *(Claude: `NotebookEdit`)*
+
+`.ipynb` is JSON that's miserable to edit via `replace`. `nbcell`
+exposes cells as text:
+
+```
+nbcell list nb.ipynb                 # index, type, first line, exec count
+nbcell show nb.ipynb 3               # cell source (and outputs with --outputs)
+nbcell edit nb.ipynb 3 --from-file cell.py
+nbcell add nb.ipynb --at 4 --type code --from-file new.py
+nbcell rm nb.ipynb 7
+```
+
+### 3.6 `wtreectl` — disposable git worktrees *(Claude: worktree isolation for agents)*
+
+Claude Code can give each subagent an isolated git worktree. `wtreectl`
+does the same for any agent:
+
+```
+wtreectl new [--branch dev/foo]   # prints the new worktree path
+wtreectl list
+wtreectl clean                    # removes worktrees with no changes
+```
+
+Lets two agent sessions work in the same repo without trampling each
+other.
+
+### 3.7 `fanout` — parallel subagent orchestration *(Claude: `Workflow`, `Agent`)* — roadmap, not agreed
+
+Runs N prompts as parallel headless agent processes (`gemini -p` /
+`claude -p`) with a concurrency cap, collecting each result as JSON in
+an output dir. A poor man's `Workflow`:
+
+```
+fanout run jobs.json --max 3 --out results/
+```
+
+Heavier than the other tools and overlaps with agent-helm's territory —
+park until there's a concrete need.
+
+## 4. Suggested tools from infra history
+
+Grounded in what the agent has already been doing per infra-Doc
+(`maintenance-and-gaps.md`, `services/source-control-and-deploy.md`,
+`services/observability.md`, the per-service "operational quick-ref"
+blocks). These help **any** agent (Claude or Gemini) administer the
+fleet, and they respect the read-only sudo policy
+(`ssh/claude-sudo-policy.md`): everything below is read-or-notify;
+mutations still go through Björn's supervised tmux flow.
+
+### 4.1 `giteactl` — Gitea repos, Actions runs and CI logs
+
+The biggest recurring friction. Today: CI status is polled ad hoc, and
+logs for private repos are only readable as zst files under
+`/srv/storage1/gitea/actions_log/…` on the Pi5. Wraps the Gitea REST +
+Actions API:
+
+```
+giteactl runs <repo> [--limit 5]          # status, branch, duration
+giteactl log <repo> <run> [--job N]       # fetches + decompresses the zst log
+giteactl wait <repo> [--timeout 30m]      # block until latest run finishes; exit 0 = green
+giteactl wait-quiet [--max-active 1]      # block until ≤N heavy builds are running
+giteactl release <repo> [<tag>]           # rolling-release assets + checksums
+```
+
+`wait-quiet` encodes the hard-learned rule "serialize pushes — >2 heavy
+builds take the Pi5 down": `giteactl wait-quiet && git push`.
+Composes with `waitfor`/`notifyr`.
+
+### 4.2 `fleet` — one-shot health snapshot of the whole homelab
+
+Every service doc ends with the same hand-rolled loop over
+`ssh pi5-claude sudo claude-docker ps/inspect …`. `fleet` does that
+loop once, properly:
+
+```
+fleet status          # containers (state, image, restarts), disk/mergerfs fill %, failed systemd units
+fleet status --host brasse-linux01
+fleet checks          # Uptime Kuma monitor states + last ntfy alerts (via notifyr read)
+```
+
+Read-only by construction (claude-docker wrapper + sudo allowlist), so
+it needs no new permissions. Output is a stable text table an agent can
+diff between runs.
+
+### 4.3 `envaudit` — compose ↔ `.env` key auditor
+
+Grounded in a real incident (`${STORAGE1}` undefined in `/srv/.env` →
+bad mount, rollback) and in maintenance-and-gaps' inline-secret
+findings:
+
+```
+envaudit check /srv/dockge-staks --env /srv/.env
+  → UNDEFINED  ${STORAGE1}   used by media-stack/compose.yaml
+  → INLINE     LDAP_ADMIN_PASSWORD  hardcoded in openldap/compose.yaml (should live in .env)
+  → UNUSED     OLD_API_KEY   defined but referenced nowhere
+```
+
+Pure text analysis of compose files — safe to run anywhere, catches the
+two failure classes that have actually happened.
+
+### 4.4 `reghelper` — docker-registry catalog & hygiene
+
+The LAN registry (`192.168.0.19:5000`) has no UI, no auth and no
+cleanup story, and the backup plan explicitly wants it slimmed:
+
+```
+reghelper ls                      # catalog + tags + image sizes
+reghelper tags <image>
+reghelper prune-plan --keep 2     # prints the delete+GC commands (does NOT run them)
+```
+
+`prune-plan` deliberately only *prints* the mutation commands for the
+supervised tmux flow — same pattern as the sudo policy.
+
+### 4.5 Backup status reader — once Backrest/restic exists
+
+future-plans.md has the whole Backrest+restic design chosen but
+unbuilt. When it lands, a `fleet backups` subcommand (last snapshot age
+per source, repo size, last check result) closes the loop — an agent
+can then *verify* backups instead of trusting them. Not a separate
+tool; park under `fleet`.
+
+### Cross-reference
+
+`/home/brasse/repos/dify-agent-tools/` already has a specced-but-unbuilt
+set of FastAPI tools (file/image sorting, face recognition, ST-card
+export…) for the Dify platform. Different runtime (HTTP tools vs CLI
+binaries), same philosophy — don't duplicate those here.
+
+## 5. Suggested build order
+
+1. `notifyr` — smallest, everything else composes with it, ntfy already runs.
+2. `giteactl` — removes the biggest daily friction (CI logs + build serialization).
+3. `waitfor` + `cronr` — turns both agents into unattended operators.
+4. `fleet` — replaces the hand-rolled health loops in every runbook.
+5. `envaudit`, `reghelper`, `pagepub`, `nbcell`, `wtreectl` — as needed.
+6. `fanout` — only if a concrete multi-agent need shows up.
